To all whom may concern.'

Be itlrnovvn that l, Homin LeRoy' Ems- BIN, a. citizen of the UnitedStates, resw at rfownsend, in the county of Broadivoter, State otMontana, have invented certain ieiv and Auseful improvements in`Wrenchesg and i do li=reby dechire the 't i'ull, clear. and exact descption the mvention, such as will enable others skilled in the art towhich it appertains to make and nge the same. t i t l I This inventionrelates to improvements in Wrenches, and particularly to .vrcnches forremoving the cover ofthe transmission goor of a Ford automobie.

@ne object' of the invention is to provide e simple and etlicient deviceof this characof which one man can Quickly ter by means L and nutstron'.

and easily remove the bolts the gear casing or cover.

Another object is to provide a device of this character by means ofwhich the nut is held stationary While the bohis'turned therethrough forremoving the seme.

Another object is 'to provide a device o this character wherein the nutand bolt *wil be i'irmly held, and danger of either becoming disengagedfrom the Wrench reduced to a minimum.

@their objects and advantages `will he o ppzirent from 'the following.description when taken in connection with the accompanying drawing.

in the drawing:

Figure l is e perspective view of a Wrench made in accordance with myinvention.

Fi 2 is a longitudinal sectional view g e through the wrench and aportion or the gear casing showing the action of the Wrench v -on thebolt and nut.

Referring particularly to the accompanying drawing l() represents, as aWhole, a frame, having tvvo substantially loi-,shaped members disposedin the some plane, as shown at ll and l2, respectively, the intermediatearm 13 being common to both of said members. rlhrough theouter arm ofthe member ll is'formed an opening 14, and alining with this opening,and formed in the intermediate arm, is an opening l5. The outer end ofthe outer arm or the memto receive or embrace the nut 16, said openingbeing' represented at 17, and shown as alining With the openings 14 andl5. Slidably disposed through the alining openings 14 and l5 is a stemor shank 18, one end of Patentedlillny 259, lt'.

which is. formed with en enlarged head 19, l,

disposed between the outer arm ot the member l2 the intermediate erm 13,seid head having a soclrct 20 formed' therein for the reception of thehead of the bolt 91. Disn formed with an angular tapering enlargel ment24E Afor reception in the socket oi a bit brace. y

y ln the operation of the' device, the U- shaped member is placed instrsddling relation to the meeting edges of the gear casing, as clearlyseen in Fig. 2, the opening 17 being engaged With the nut, While thesocket is disposedto receive the head of the bolt. The spring Will forcethe socket forward so as to properly hold the-bolt head, and by turningthe brace the stem Will be rotated in the alining openings, therebyaccomplishingthe turning of the bolt, While the arm of th'e member 10`rmly holds the nut. Thus the necessity of having a second man to holdthe bolt or nut While the other is turned is completely obviated, oneman beingable to remove both the bolt and nut, alone. Asthe bolt recedesfrom the nut, the spring is put under tension, automatically, therebyincreasing the holding power thereof.

lt Will be noted that the device is of simple construction, and that itis formed of a minimum number of parts, thereby contributing to areduction of the cost of manufacture.

What is claimed is:

A Wrench comprising a frame including av ing formed With an openingalining lWith the first opening, the arm of the other yoke member being`formed with a nut receiving and holding opening, a stem slidably ,diss

posed through the alining openings, a bi(-J stop member and the saidsecond-named brace engaging member formed on one end arm.
